ec/google/chromeec: let platform prepare for reboot when resetting EC
This fixes an issue on systems where the S3 state in the pm1 control registers are not cleared when vboot determines recovery mode is required on an S3 resume. The EC code will reboot the system knowing that the EC was in RW. However, on subsequent entry into romstage the S3 path will be taken and fails to recover cbmem -- forcing another reboot. To work around that, signal to the platform a reboot is happening and let the platform perform the necessary fix ups to the register state.
